Researchers achieved real-time detection of low gas concentrations using a coherent control strategy that offers promise for real-time monitoring in environmental, health, and industrial applications. “Most gases are present in small amounts, so detecting gases at low concentrations is important in a wide variety of industries and applications,” said research team leader Simon Angstenberger from the University of Stuttgart in Germany. “Unlike other trace gas detection methods that rely on photoacoustics, ours is not limited to specific gases and does not require prior knowledge of the gas that might be present.” The team next plans to explore the limitations of the new technology to determine its maximum speed and lowest sensing concentration.
